Just an update. I moved the bottle and made some changes as suggested here. Below is an outline of what I did, in case it might help anyone with a ZX-14 who is looking for a better spot to mount a bottle:
I am running a Catalyst step seat at the dragstrip, and I called it into duty for the mile. It is hollow underneath and gives some room for mounting. I also ordered some smaller 3.5 oz. CO2 bottles, figuring they would be easier to deal with:
I cut a bracket from a piece of scrap aluminum:
Instead of stainless hose clamps, I used heavy exhaust clamps. These are much more secure. I drilled the mounting bracket accordingly:
Here is the spot where the bracket will mount:
I removed the seat latch and attached my new bracket assembly solidly to the subframe:
Here you can see that the seat provides plenty of clearance and coverage for the bottle and regulator assembly:
There are a few more things to do, but I think this is much improved from a safety standpoint. If any of you have a ZX-14, you might want to look into the Catalyst seat for added room.
